SPIKE BASE FOR ATHLETIC SHOES.

Application led September 13, 1927. Serial No. 219,284.

My invention relates to improvements in spike bases for athletic shoes, such as track slices, and the object of the invention is to provide an improved base, which is incorporated within the sole of the shoe and to which the spike issecured, whereby a very rigid and secure support is provided for the spike and also in which the spike base itself will not work loose in the sole; a further object is to provide a spike base of very light and inexpensive construction and which may be conveniently built into the shoe during manufacture without complicating the manufacturing process or increasing the cost.

Other objects will appear in the courseof the following specification.

My invention consists in the construction and' arrangement of parts, all as hereinafter more particularly described and illustrated in thel accompanying drawings in which Fig. 1 is a bottom plan View of a portion of an athletic shoe, having my invention applied thereto.

Fig. 2 is a fragmentary section on the line 2- -2 of Fig. l.

Fig. 3 is an elevation of my improved spike base and spike used therewith, the base and spike being shown separated and a washer being in section.

Fig. 4 is a top plan view of Fig. 3.

In the drawings like characters of ref- -erence in dicate corresponding parts in the various views.

In a shoe employing my improved base, the, outer sole 1 is formed of two superimposed layers 5 and 6 and these layers are provided with aligned orifices 7 and 8, which together form an orifice extending entirely through the outsole. These orifices would be disposed about the outer sole at the points where spikcsare to be attached.

My base comprises an internally threaded sleeve 9 which carries a comparatively thin fiange 10 proj ect-ing outwardly therefrom and positioned intermediately of its length, the plane of this ange being perpendicular to the axis of the sleeve.

The construction is such that the sleeve 9 ext-endsperpendicularly on either side of the flange 10.

Projecting from one face of the flange 10 are spicular projections 11 which may be formed by punching the flange. v

The spike 12 used is of the usual form havinga nut portion .13` and a threaded shank 14 adapted to fit within the internally threaded sleeve 9, only in my case the shank 14 is longer than usual and is the full length of the sleeve 9.

A washer 15 is used upon the spike.

lInconstructing a shoe according to my 1nvention the two layers 5 and 6 of the outersole are provided with the aligned orifices 7 and 8 as before mentioned.

The spike bases are then mounted between these layers so that ythe two projecting ends of the sleeve 9 enter these orifices and the two 'layers 5 and 6 are then pressed together. This forces the sleeves 9 tightly into the orifices in the outer sole and the flanges 10 are firmly held and anchored between the layers. Also in this operation the spicular projections 1l penetrate into one layer of the outsole.

When the outsole has thus been formed with the bases therein, the formation of the shoe including the insole 16 is completed in the usual manner.

It will thus be seen that in a shoe made in accordance with my invention the spike bases are very rigidly and securely anchoredA within the outersole.

The spikes 12 are simply screwed into the bases in the usual manner and each carries a bearing washer 15.

It is to be noted that with my base the sleeve 9 is securely supported within the sole both 'above and below the fiange 10 and for the entire thickness of the sole and that the shank 14 of the s ike has a. bearing for the entire length of t e sleeve.

This provides an exceptionally strong and rigid support for the spike so that when subjject to the strain in use the spike cannot wobble or work loose laterally.

The spicular projections '11 prevent the fianges 10 from turning when the spikes are screwed into the bases.

From the foregoing it will be evident-that I have devised an improved spike base which will provide a very strong, rigid and secure mounting for the spikes in athletic shoes and whereby the objects of my invention. have been attained.

Various modifications may be made in my invention without departing form the spirit thereof or the scope of the claims and therefore the exact forms shown are to be taken as illustrative only and not in a 4limiting sense and I desire, that only such limitations shall be placed thereon as are imposed by the prior art or are specifically set forth in the appended claim.

What I claim as my invention is In an athletic shoe, in combination, an outsole formed of'tWo superimposed layers, aligned orifices in said layers, a spike base comprising an internally threaded sleeve, a ange project-ing outwardly from the periphery thereof and positioned intermediately of the length of the sleeve, the plane of the flange bein perpendicular to the axis of the sleeve, sai base mounted Within the outsole so that the flange lies between the two layers thereof and the sleeve extends into tlieuforesaid aligned orifices in the two layers of the outsole, the ends of the sleeve being flush with the top and bottom faces of the outsole.
